What we don't have is an earthly alter with an RC priest presiding over it.
"We have an altar from which those who serve the tabernacle have no right to eat."
"Take, and eat, every one of you, for THIS IS MY BODY, which will be given up for you"
"Christ our Passover is sacrificed, THEREFORE LET US KEEP THE FEAST"
The truth is staring you in the face, but you will have none of it.
